I’m trying to remove my Delta bass from its cab, because it has a scratchy pot and I’m going to try to blow it out with a air can duster. I can’t get the dang thing out of the cab. It’s like it’s stuck in their. It looks like it’s rack mountable so it should come right out, but no luck. Anybody ever do this? I don’t want to damage it, but it should be removable for service, no?
